Several people were killed and dozens reportedly injured after a major fire erupted at Canadian Forces Base Wainwright in Alberta on Saturday, prompting a large emergency response as powerful winds drove flames into surrounding rural areas.
Defence Minister David McGuinty confirmed fatalities and injuries but did not provide an official casualty count or establish the cause of the incident.
Canadian broadcaster Global News reported that at least seven people were killed and dozens injured after a gas line or gas well was reportedly struck during a live-fire training exercise, citing unnamed military sources.
Authorities have not independently confirmed that account.
Prime Minister Mark Carney described the emergency as a serious incident that caused a major fire and expressed sympathy for affected military personnel.
The blaze spread rapidly beyond the base's perimeter fence as wind gusts reached approximately 100km/h, according to local reports.
The Municipal District of Wainwright said firefighters were responding to the spreading flames, while subsequent indications from local officials suggested the fire had been contained.
McGuinty described the situation as highly active and delicate, saying he could not recall a comparable incident in recent memory.
The scale of the casualties placed significant pressure on medical facilities in Edmonton, approximately 180 kilometres northwest of the base.
Royal Alexandra Hospital declared a code orange, activating emergency procedures for a mass-casualty incident.
Emergency physician Warren Thirsk warned that the influx of patients was overwhelming healthcare resources, with casualties being transported to hospitals across Edmonton.
Federal, provincial and local authorities coordinated with the Canadian Armed Forces as emergency crews continued their response.
Residents were urged to avoid affected areas and keep roads accessible.
Alberta Premier Danielle Smith described the fire as tragic, while Saskatchewan deployed additional resources and British Columbia offered assistance.
Wainwright Mayor Bruce Pugh warned that the disaster could become the community's largest mass-casualty event.
The incident occurred two days before Albertans were scheduled to vote on whether to begin a legal process toward a potential provincial secession referendum.
